Black holes are not necessarily eternal in the simplest quantum description. Stephen Hawking's work showed that quantum effects near an event horizon allow black holes to emit thermal radiation and therefore lose mass extremely slowly.
What the science says
For astrophysical black holes, Hawking radiation is extraordinarily weak. A black hole with stellar or supermassive mass is colder than many surrounding environments and would gain or lose matter through ordinary astrophysical processes far faster than it evaporates today.
How the process works
As the universe expands and backgrounds cool, an isolated black hole could eventually lose more energy than it absorbs. The evaporation time for a stellar-mass black hole is vastly longer than the current age of the universe, so this process is not something astronomers expect to watch directly.
What scientists measure
The late stages of evaporation involve physics at energy scales where a complete quantum theory of gravity is still lacking. That uncertainty is tied to the black-hole information problem: how information about matter that fell in is represented in the final quantum description.
Limits and open questions
So the scientifically careful answer is that black holes can, in theory, lose mass through Hawking radiation, but the fate of real black holes unfolds over almost unimaginable timescales and the final stage remains an open theoretical question.
Why this topic matters
Understanding Can Black Holes Die helps connect individual observations to the larger scientific framework. Reliable explanations separate measured evidence from speculation, make uncertainty visible, and give readers a basis for interpreting new research as it appears.
